weather--app# Weather Forecast Application.

A fully functional Python weather application that fetches real-time weather data and forecasts using the OpenWeatherMap API...

Features

✅ Current Weather: Get real-time weather information for any city

• Temperature (actual and "feels like")
• Weather conditions
• Humidity and pressure
• Wind speed
• Sunrise and sunset times

✅ Weather Forecast: Get 5-day weather forecasts

• Hourly breakdown for the first 24 hours
• Temperature trends
• Weather conditions
• Humidity tracking

✅ User-Friendly Interface: Interactive menu system

✅ Error Handling: Robust error handling for API requests

Installation

1. Clone or navigate to the project directory

cd /workspaces/codespaces-blank/weather-app

2. Install dependencies

pip install -r requirements.txt

3. Get an API Key

1. Go to OpenWeatherMap API
2. Sign up for a free account
3. Get your API key from the dashboard
4. Copy your API key

4. Configure the API Key

Edit main.py and replace the API_KEY value:

API_KEY = "your_actual_api_key_here"

Or create a .env file:

cp .env.example .env

Then edit .env and add your actual API key.

Usage

Run the application:

python main.py

The application will present a menu with options:

1. Get current weather - Enter a city name to see current conditions
2. Get weather forecast - Enter a city name to see the 5-day forecast
3. Exit - Close the application

Examples

Enter city name: London
Enter city name: New York
Enter city name: Tokyo

How It Works

Architecture

The application uses an object-oriented approach with the WeatherApp class:

• __init__(api_key) - Initialize with your OpenWeatherMap API key
• get_current_weather(city) - Fetch current weather data
• get_forecast(city) - Fetch 5-day weather forecast
• display_current_weather() - Format and display current weather
• display_forecast() - Format and display forecast data

API Integration

Uses the free OpenWeatherMap API:

• Current Weather Endpoint: /weather
• Forecast Endpoint: /forecast

Data Processing

• Converts Unix timestamps to readable dates/times
• Formats temperatures in Celsius (configurable)
• Groups forecast data by day
• Displays data in an easy-to-read format

Technical Details

• Language: Python 3.x
• Key Libraries: requests for HTTP calls
• Type Hints: Includes proper type annotations
• Error Handling: Try-except blocks for API failures

Troubleshooting

"Error fetching current weather"

• Verify your API key is correct
• Check your internet connection
• Ensure the city name is valid

API Key Issues

• Sign up for a free account at openweathermap.org
• Wait a few minutes after registration for the key to activate
• Check that you copied the entire key correctly

Network Issues

• Check your internet connection
• Verify the OpenWeatherMap API is not down
• Try a different city

Future Enhancements

• Add caching to reduce API calls
• Store favorite cities
• Add weather alerts
• Support for coordinates (latitude/longitude)
• Export data to CSV/JSON
• Add weather icons/emojis for conditions
• Background tasks for periodic updates
• Web UI using Flask/Django
